Abstract

The uncontrolled use of sound systems in mosques, especially after the call to prayer and iqomah, often leads to waste of energy and disturbances to the surrounding environment. This research aims to develop an Arduino-based automation system that can set the time of turning on and off the sound system in the mosque according to the adhan schedule, in order to improve operational efficiency and reduce electricity consumption. The system is designed using an Arduino UNO microcontroller, which regulates the sound device via a relay based on manually entered timing. Testing was carried out using Wokwi software simulations, and the results were then applied to a physical prototype. Testing is carried out with various time settings (5, 10, 15, and 20 minutes) to assess the accuracy and reliability of the system. The test results showed that the system was able to control the sound device with a 100% success rate in all the times tested. This system has proven to be effective in reducing the duration of unnecessary use of sound devices, potentially saving energy. The developed system provides a practical solution to reduce energy waste in mosques and improve the operational management of sound devices. Further implementation of this system in mosques can provide significant social and environmental benefits, especially in terms of congregational comfort and energy savings. Field testing as well as the development of IoT-based technologies in the future can expand the functionality of these systems.

Abstract

Character education is one of the important aspects in forming a good personality in each individual. Good character will have a positive impact on the social, emotional, and academic life of students. The 7 Habits of Great Indonesian Children Movement Program is designed as a strategic step to form individuals who are not only academically intelligent, but also have strong characters that are the foundation of the nation's success in the future. The main objective of this movement is to create a golden generation of Indonesia in 2045. By instilling positive habits from an early age, it is hoped that Indonesian children can grow into healthy, intelligent, characterful individuals who contribute positively to the nation and state. One of the State Vocational Schools in Pekanbaru has implemented the 7 habits of great Indonesian children movement, namely at State Vocational School 3 Pekanbaru.

Abstract

The development of information technology has encouraged the use of machine learning algorithms in various fields, including in the analysis and prediction of weather conditions. This study aims to analyze and compare the performance of two machine learning algorithms, namely K-Nearest Neighbors (KNN) and Random Forest, in the classification of weather conditions based on historical meteorological data. The dataset used includes features such as rainfall, maximum temperature, minimum temperature, and wind speed, with target categories in the form of weather types such as rain, sunny, fog, drizzle, and snow. The process includes data pre-processing, feature scaling, training and test data sharing, and model training using the scikit-learn library. Performance evaluations are conducted using accuracy, precision, recall, and F1-score metrics. The results showed that the Random Forest model had higher accuracy (82%) than KNN (78%), with more stable performance in the majority class. However, both models experienced significant performance declines in minority classes due to data imbalances. The study recommends further optimizations such as class balancing and model parameter selection to improve the overall accuracy of weather classification.

Abstract

Dalam proses produksi salah satu kegiatan yang umum adalah material handling yaitu penanganan atau pemindahan bahan baku dari satu proses ke proses yang lainya. Proses pemindahan material atau material handling dibutuhkan pesawat angkat dan angkut. Salah satu pesawat angkut yang digunakan adalah mesin Screw conveyor. Mesin digunakan untuk memindahkan material berupa clay yaitu berupa butiran butiran tanah yang sudah dikondisikan dengan ukuran tertentu yaitu berukuran 5mm sampai 30mm. Bagian pada mesin ini yang sering mengalami kerusakan adalah bagian bearing, hal ini dikarenakan semua beban untuk mendorong material bertumpu langsung dengan bearing. Untuk menentukan kekuatan bearing yang dipakai maka harus dibuat dulu rancangan dasar dari mesin tersebut, yaitu kapasitas mesin, jenis material, gaya yang bekerja pada bagian bearing. Disini telah didapatkan data kapasitas mesin screw conveyor adalah 11.000 kg/jam, kekuatan bearing secara perhitungan yaitu Bearing QJ304: 15.637 jam, Bearing NU304: 38.683 jam, dan Bearing 22316: 50.937 jam. Untuk mendapatkan kondisi aktual bagian bearing yaitu pengukuran vibrasi. Dalam hal vibrasi alat ukur akan menunjukan besarnya velocity. Velocity adalah jumlah waktu yang dibutuhkan ketika terjadinya displacement atau kecepatan getaran suatu benda. Secara garis besar Velocity mewakili kondisi kerusakan bearing yang diaktualisaikan dengan niali 0-11 yaitu merujuk pada Standard ISO 10816-3. Sehingga akan didapatkan hasil perbandingan dari perhitungan perencanaan mesin dan aktualnya.
